Abstract
The utility model discloses a high pressure manual cut-off valve which is mainly used on a high pressure pipeline. The high pressure manual cut-off valve comprises a valve spool connected with a hand wheel and a valve body assembled with the valve spool through a flange. A sealing element assembly capable of bearing ultrahigh pressure and comprising a seal ring (11), an O-ring (12) and a retaining ring (13) is mounted at the end of the valve spool (5); a conical surface hard seal is arranged between the valve spool (5) and the valve body (4); and a safety message sending device for testing the position of the valve spool is arranged on the valve body (4). Through the sealing element assembly capable of bearing ultrahigh pressure and the conical surface hard seal arranged between the valve spool and the valve body, the function of bearing ultrahigh pressure sealing can be achieved, and the high pressure hydraulic oil in an operating cylinder can be prevented from flowing out. The high pressure manual cut-off valve not only provides convenience for maintenance operation on the high pressure pipeline, but also ensures the safe reliability of sealing during maintenance operation. By adopting the high pressure manual cut-off valve, the shortcomings that during conventional maintenance, the oil loss is large, the environmental pollution is severe, and the maintenance is inconvenient can be overcome.
Description
Technical field
The utility model is a kind of valve member that is mainly used in the maintenance of macrotype isostatic pressing machine hydraulic system, and more particularly, the utility model is the hand stop valve that is applied on the macrotype isostatic pressing machine clutch release slave cylinder pressure duct.
Background technique
Along with the continuous expansion of isostatic pressing technology application, also more and more to the demand of large-scale rolled-up stock, macrotype isostatic pressing machine also increases thereupon.But when the macrotype isostatic pressing machine hydraulic system is keeped in repair, because existing macrotype isostatic pressing machine is not provided with this functional valve member on pressure duct, usually because remaining hydraulic oil liquid can not drain fully in the clutch release slave cylinder, cause a large amount of fluid in clutch release slave cylinder, to flow out, make fluid loss and befouling environment, and bring many inconvenience for the maintenance of pressure duct.
The model utility content
It is a kind of simple and convenient that the purpose of this utility model is to provide, easy operating, safe and reliable high pressure hand-operated stop valve, the defective of fluid loss, befouling environment, inconvenient maintenance when keeping in repair to overcome pressure duct.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of high pressure hand-operated stop valve, comprise the spool of a connection handwheel and the valve body by flange plate assembling spool, it is characterized in that, the Sealing group of the seal ring, O shape circle and the back-up ring composition that bear ultrahigh pressure is housed on the annular groove of described spool termination, between spool and valve body, be provided with the conical surface and seal firmly, a safe signal transmitter that valve element position is detected is set on the described valve body
The utlity model has following beneficial effect:
Simple in structure, easy operating, safe and reliable.The utility model adopts and be shaped on the Sealing group that can bear ultrahigh pressure on spool, and the conical surface that adopts between spool and the valve body seals firmly, has promptly reached the effect that can bear superhigh pressure sealing, has prevented the outflow of clutch release slave cylinder inner high voltage hydraulic oil liquid again.It not only provides the convenience of maintenance operation on pressure duct, and has guaranteed the safety reliability of tight seal in the maintenance operation.The defective that when having overcome traditional maintenance, the fluid loss is big, environmental pollution serious, maintenance is very inconvenient.
On macrotype isostatic pressing machine clutch release slave cylinder pressure duct, increase the ultrahigh pressure hand stop valve open in usual that this spool is in open mode fully, guaranteed that pipeline is safe and smooth.On valve body, be provided with one can to valve element position detect near switch, the drawback that the ultrahigh pressure hand stop valve is not opened when having avoided press work.When near the switch sender, the ultrahigh pressure hand stop valve is in open mode.
Description of drawings
Fig. 1 is the organigram of the utility model high pressure hand-operated stop valve.
Among the figure: 1 handwheel, 2 adjusting screw rods, 3 flange plate, 4 valve bodies, 5 spools, 6 double-screw bolts, 7 nuts, 8 packing rings, 9 near switch, and 10 near switch bracket, 11 superhigh pressure sealing circles, 12O shape circle, 13 back-up rings.
Embodiment
In the utility model ultrahigh pressure hand stop valve shown in Figure 1, the spool 5 that connects handwheel 1 is assemblied in the valve body valve opening by flange plate 3.The Sealing group of seal ring 11, O shape circle 12 and back-up ring 13 compositions that can bear ultrahigh pressure can be housed on the annular groove of described spool 5 terminations successively.Also being provided with the conical surface between the contact seal face in the middle of spool 5 and the valve body 4 seals firmly.The adjusting screw rod 2 that handwheel 1 connects firmly connects the spool 5 that has " worker " annular groove.Flange plate 3 connects firmly on valve body 4 by the double-screw bolt on it 6, nut 7 and packing ring 8.Pipeline is unimpeded during for the assurance supercharging, also is provided with one by the safe signal transmitter near switch 9 senders in the right ports of valve body 4.This safe signal transmitter by be arranged on connect firmly in the valve body 4 right radial holes near switch bracket 10 and connect firmly forming on it near switch 9.Be arranged near switch 9 on the cylinder of described valve body 4.When press is worked, near switch 9 senders, show that part spool 5 is opened fully, can carry out supercharging this moment to clutch release slave cylinder, otherwise can not pressurize to clutch release slave cylinder.
Quit work when keeping in repair at press, handwheel rotates and screws off spool 5 and valve body 4 sealings, makes spool 5 sealing pressure ducts, prevents that hydraulic oil liquid flows out in the clutch release slave cylinder, and can carry out maintenance work.After maintenance is finished, this valve is opened, rotated handwheel 1, mention spool 5, can make pipeline keep unimpeded.
